Shredder, the most successful chess program ever, is now also available for the iPhone. You can play against Shredder, analyze with him and solve chess puzzles. It offers the usual Shredder standard for your pocket.

In addition to the outstanding playing strength of the 12 times computer chess world champion, Shredder is also able to mimic the play of a human chess player with any playing strength. He even deliberately makes typical human mistakes in those levels.

Solve 1000 built in chess puzzles. Shredder keeps track of your performance and offers advice if needed.

You can adjust Shredder’s playing strength from beginner to master level. If you like, Shredder automatically adjusts his strength to yours. He even calculates an Elo rating for you. This is how the playing strength of chess players is typically measured.

During the game a coach is watching your moves and warns you if you are about to make a mistake.

Becoming a legacy application

No updates of the engine and staying far behind Smallfish.

Supercruller ,

Due for an UI refresh

Needs updates to enhance playability and strength but also to modernize the User Inerface which looks very tired

great chess engine, interface could be better

As everyone else said, the engine is excellent -- one of the best if not the very best here.

Some of the buttons and menu choices aren't intuitive and seem more difficult to find/use than some other chess games...which admittedly is due in part to more options and complexity than some other games, but the interface could still be improved.

A note to the developer: is the splash screen really necessary? I want to touch the icon and see the chessboard immediately, not some splash screen. I have deleted some paid apps (and bought others as replacements) just because the splash screen annoyed me every time I used them. I'll put up with it in this case because it's a great chess app, but I don't like it splash screens on apps and am not alone in this. It ain't Windoze.
